Objective Decreased clearance of apoptotic cells is suggested to be a major pathogenic factor in systemic lupus erythematosus (SLE). The aim of this study was to investigate whether the binding of SLE autoantibodies to apoptotic cells influences the phagocytosis of these cells by macrophages. Methods Apoptosis was induced in a human T cell line (Jurkat) and a keratinocyte cell line (HaCaT) by ultraviolet B irradiation. Binding of purified IgG from 26 SLE patients and 15 healthy controls to apoptotic cells was assessed by flow cytometry and Western blotting. Phagocytosis of IgG‐opsonized apoptotic cells by monocyte‐derived macrophages was assessed by light microscopy. Similar experiments were performed with a monoclonal antibody against SSA/Ro and IgG fractions from 5 patients with Sjögren's syndrome (SS) and 5 patients with rheumatoid arthritis (RA). Results IgG fractions from all 26 SLE patients bound to late apoptotic, but not early apoptotic, cells. IgG fractions isolated from SLE patients with different autoantibody profiles showed comparable levels of binding. IgG fractions from healthy controls did not bind. Opsonization of apoptotic cells with IgG fractions from SLE patients resulted in a significant inhibition of phagocytosis as compared with healthy control IgG fractions. A monoclonal antibody directed against SSA/Ro and IgG isolated from 5 antinuclear antibody (ANA)–positive patients with SS were also able to elicit these effects, whereas IgG from 5 ANA‐negative patients with RA did not. The inhibitory effect of patient IgG was abolished by blocking either the Fcγ receptors (FcγR) or the constant region of IgG, using a specific Fc‐blocking peptide. Conclusion Autoantibodies from SLE patients are able to opsonize apoptotic cells and inhibit their uptake by macrophages via an FcγR‐dependent mechanism.
The objective of this study was to establish the relationship between Candida vaginalis and (pre)neoplasia and the prevalence of Candida and (pre)neoplasia related to age and ethnicity. Data were collected from 445,671 asymptomatic women invited for mass screening between 1995 and 2002 and coded according to the Dutch cervical smear coding system (KOPAC) with six grades for (pre)neoplastic changes. Prevalence and relative risks (RRs) were established for Candida and squamous abnormalities in Dutch women and four groups of immigrants. The prevalence of Candida is significantly higher in the cohort of 30-year-old women and lower in the cohorts of 45-, 50-, 55-, and 60-year-old women. The RR of having Candida was higher for Surinamese women (1.24; CI 1.08-1.42). Furthermore, the RR of having mild dysplasia was higher for Surinamese women (1.47; CI 1.14-1.89) and for women born in other countries than in The Netherlands, Turkey, and Morocco (1.36; CI 1.13-1.62). No statistically significant relationship between (pre)neoplasia and Candida was observed. C. vaginalis is more frequent among Surinamese women. Presence of Candida is not associated with an increased risk for squamous abnormalities; therefore, women carrying Candida are not at an increased risk of developing cervical cancer.
In the small country of The Netherlands, we found a high PPV in surgical management of POP and UI with respect to the choice for surgical treatment and the type of surgery. This finding might be due to the absence of clearly defined guidelines. Studies with respect to conservative versus surgical treatment and the type of surgery are of need to establish evidence-based guidelines.
In a prospective cohort study, 10 symptomatic women with recurrent vulvovaginal candidiasis were taught how to prepare vaginal smears of their own vaginal fluids on days 7, 14, 21, and 28. The 40 smears were stained with the PAS-method and examined by three different cytopathologists for presence of Candida. Thereafter, the smears were restained with Giemsa-stain to determine presence of lactobacilli, Gardnerella vaginalis ("clue cells") and neutrophils. All three cytopathologists unequivocally established Candida blastospores and (pseudo)hyphae in 27 out of the 40 PAS-stained vaginal smears, whereas in the remaining 13 smears Candida was not found. All 10 patients had Candida in their smears during the second half of their menstrual cycle.Self sampled smears prove to be reliable for establishing the presence of Candida in symptomatic patients with candidiasis. Candida is associated with a lactobacillus-predominated vaginal flora, but with the absence of Gardnerella vaginalis. Further studies may be directed towards the interaction between the various members of the vaginal flora. This study should open molecular methodology for determining the possible interactions of lactobacilli and Candida.
Objective: To evaluate the long-term outcomes of single-incision midurethral slings (SIMS) in real-life practice.Study Design: This retrospective, single-arm, patient cohort study was performed in a large Dutch teaching hospital, including 397 consecutive women who underwent a SIMS-procedure between 2009 and 2018. Data were obtained through questionnaires and patient record study. Subjective improvement was the primary outcome, defined as a Patient Global Impression of Improvement (PGI-I) of '(very) much better'. Secondary outcomes were subjective cure rate (defined as a negative Urogenital Distress Inventory -item 4 'Do you experience involuntary urine leakage related to physical activity, coughing or sneezing?'), complication rate and sling failure (defined as the need for additional research or treatment for persisting stress urinary incontinence (SUI)). All data was analysed with a statistical significance level of 5%. Results: The mean follow-up time was 54 months. All patients received SIMS (Ajust Ò or Altis Ò ). Of all respondents, 75% reported a (very) much improved burden of disease. The subjective cure rate was 61%. In 93 patients a total of 120 complications were registered. In 10% of patients a sling failure was observed, 76% of these failures appeared in the first two years post-surgery. Conclusion: This study showed that, in real life practice, SIMS are both effective and safe over a long period of time.
Aims To evaluate the adjustable single‐incision sling (Ajust®) in the treatment of stress urinary incontinence (SUI), when placed under conscious sedation with local infiltration, using the cough test during surgery. Methods In this multicenter observational study, 90 women who had moderate to severe SUI, were asked to have the Ajust® procedure performed under sedation with local infiltration with levobupivacain. This allowed for a perioperative cough test to adjust the sling to the urethra till continence was reached. The primary outcome of the study was subjective cure of stress incontinence at 1 year follow up. Secondary objectives were objective and subjective improvement, complications during and after the procedure, and postoperative pain scores. These results were compared with the results of a historical control group of 96 patients who received their Ajust® under general or regional (spinal) anesthesia. Results At 6 weeks and 12 months, there were no statistical significant differences in the results for subjective cure (83.6% and 71.6% sedation group, 88.4% and 77.2% general/regional anesthesia group), objective cure (96% and 86.9% sedation group, 88.1% and 91.8% general/regional anesthesia group), de novo urgency (10.5% and 6.7% sedation group, 7.1% and 24.1% general/regional anesthesia group) and the patients global impression of improvement (96% and 89.2% sedation group, 91.4% and 84.4% general/regional anesthesia group). Conclusion The performance of a cough test during the placement of an adjustable single‐incision sling for the treatment of SUI does not affect the functional outcome, and is therefore not necessary.
Objectives: Midurethral slings are considered the gold standard for the surgical treatment of stress-urinary incontinence (SUI), with an efficacy up to 80%. Another therapeutic option is the use of bulking agents, which create an artificial mass into the urethral submucosa, with an efficacy varying from 64% to 74%. Although bulking agents have a lower risk of complications than midurethral sling surgery, they are mainly used in case a midurethral sling is not an option or if midurethral sling surgery failed to cure stress urinary incontinence. In this study we offer all patients with SUI in secondary care a choice between a single incision midurethral sling procedure and treatment with a bulking agent. We want to examine patient preference and patient satisfaction for both procedures. We expect that offering both interventions in combination with standardized counselling will result in high patient satisfaction. Design: In this non-randomized controlled trial 266 patients will be objectively counselled for both interventions, after which all patients will choose between single-incision midurethral slings (SIMS) and Polyacrylamide hydrogel (PAHG), followed by the standard care procedure for women with SUI. Participants/Materials, Setting, Methods: From 1 January 2021 onwards, all consecutive adult patients (between 18 and 80 years of age) attending the outpatient gynaecology department with objectively confirmed, moderate to severe SUI will be eligible for enrolment in this non-randomized study. The primary outcome is patient satisfaction at 1 year, measured by the Patient Global Impression of Improvement; secondary outcomes are patient satisfaction at 3 months, objective and subjective cure at 3 months and 1 year, adverse events, postoperative pain and cost-effectiveness. Differences in outcome measures will be assessed through logistic and linear regression analyses, both unadjusted and adjusted with covariate adjustment using the propensity score. Results: No results are available yet. Limitations: The major disadvantage of this study design is the potential confounding bias. We intend to eliminate this bias by applying propensity scoring. Conclusion: By designing a non-randomized patient preference trial, we not only expect to demonstrate high patient satisfaction with both interventions, but also provide insight in the possible role of PAHG-injections in the treatment of female SUI as a first-choice non-conservative treatment. Trial Registration: This study is retrospectively registered at the Dutch Trial Registry on 22-03-2021 under the number NL9353.
